CARL 0. YOUNGREN, DOWNIITG, WISCONSIN.

FOLDING UMBRELLA.

To all whom it may concern:

` Be it known that I, CARL O. YOUNGREN, a citizen of the United States, residing at Downing, in the county of Dunn, State of Wisconsin, have invented a new and useful Folding Umbrella; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to certain new and useful improvements in umbrellas, and has for its object to provide a device of this character which embodies novel features of construction whereby it can be collapsed and packed into a small amountvof space, thereby enabling it to be carried in the pocket or packed without difculty 1n a suitcase or trunk.

Further objects of the invention are to provide a folding umbrella which is simple and inexpensive in its construction, which can be readily expanded or collapsed, which is securely locked against accidental collapsing when in use, and which has no delicate parts to break and get out of repair.

With these and other objects in View, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claim.

For a full understanding'of the invention, reference is to be had to the following description and accompanying drawings, in whichzi Figure l is a vertical longitudinal sectional view through a folding umbrella, constructed in accordance with the invention, portions being broken away, the umbrella being shown in a distended position.

Fig. 2 is a similar view, showing the umbrella in a collapsed position.

Fig. 8 is a detail view of the locking mechanism for holding the extensible ribs in an expanded condition.

Fig. l is a view similar to Fig. 3, showing the locking mechanism in the position assumed when the umbrella is collapsed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In carrying out the invention the ribs of the umbrella are formed in inner sections l Speccation of Letters Patent. Patentgdl Sgpto 1L p91?,

and outer sections 2, said sections having a `sliding connection with each other, so that the outersections 2 can be telescoped upon the inner sections l when the umbrella is collapsed. The inner ends of the sections l are pivotally connected in the usual manner to ahead 3 at the upper end of a sleeve et. The outer end of each of the sections l is beveled at la to avoid any sharp corners or projections which would tend to catch upon and tear the fabric cover, and a downwardly extending keeper 5 is provided at a point slightly spaced from the said beveled end. Each cuter section 2 isarranged to slide against the lower face of the inner section l, being received within the keeper 5 of the inner section, and being provided at a point spaced from the inner end thereof with an upwardly extending keeper 6 which slidably receives the inner rib section l.

\ The extreme inner end of each outer rib section 2. is provided with a bifurcated bearing 7 which is straddled by the bifurcated end 9 of the brace l0 and pivotally connectedtheretoby a pivot' pin 8. The opposite end of the brace l0 is pivotally connected in the usual manner to a runner ll which is slidable upon the stick, said runner carrying pivoted latch members 12 which are adapted to engage a shoulder 13 on the sleeve 4 when the umbrella is distended for use. Springs 14 engage the latch members 12`to normally hold them in operative position, although by pressing inwardly with the lingers upon the rear ends of the latch. members l2, the latter can be readily disengaged from the shoulder 13 of the sleeve Il. Pivotally mountedupon each of the pivot pins 8, and arranged within the bifurcated bearing 7 of each of the outer rib sections 2, is a dog l5, said dogs being adapted to sirinO into engagement with notches 16 in b C t? tion, said springs 19 being clamped and rei tained in position b v the lower portions of the keepers 6. .As previously explained, the

tions .2, y'the kforked end 9 of the saidibraces will be brought into engagement with the extensions 18 of the dogs 15 so as to swing the latter into inoperative position. With the dogs 15 thus engaged from the notches A16, the outer rib sections 2 can be telescoped inwardly upon the inner rib sections 1, so 'as to decrease the length of the ribs by about one half.

The umbrella stick is formed in .two main telescoping sections 2O and `21, the upper section 2O being adapted to telescope entirely within the lower section 21. A shorter handle section 22 is telescopically mounted upon the lower end .of the section 21, while the before mentioned sleeve 4 is adapted to telescope overthe upper end of the section 21 when the umbrella is collapsed. In this connection it may be noted that the section 20 extends centrally through the f-sleeve L1 and is rigidly secured to thelhead 3 ..at the upper end of the sleeve, although there is a sufficient amount of space between thesaid sleeve and the section 20 for the receptionfof the upper end-of the section 21 when the device is collapsed.

The lower extremity of each of the sections 2O and `21 is very slightly enlar ed, as indicated at 20zt and 21, respective y, for engagement with interior ribs 22 and 21h' o'n the handle 22 and section 21, respectively, to prevent the members from pulling apart. At points slightly spaced from .the lower ends thereof the members 20 and 21 are each provided with a pair of diametrically opposed openings 241 which are adapted toreceive heads 25 on the ends of U.shaped springs 26, said springs being compressed and inserted within the members. These heads 25 are adapted to extend through the openings 24 into engagement with notches 27 in theupper ends ofthe member 21 and handle member 22, thereby prevent- A.themembers when in use.

:1t ispdesiredto collapsewthe stick, it is merely ing `accidental collapsingy or 4telescoping of However, when necessary to disengage the heads 25 from the notches v27 by pressing inwardly upon the heads, and then telescope the several memberszofthe stick upon each other, `the member 2O fitting completely within the member 2l, and the member 21 being in turn received within the ,handle secti0n22 and the sleeve et. The enti-re zumbrella can thus be collapsed land folded very compactly, there- Iby `enabling it to be easily carried in the pocket, `or `packed in a suitcase or trunk.

Havingthus described theinventiomwhat I claim fas newcand :desire to secure by Letters Patent, is:--` 4 A folding iunbre'lla, including a stick, pivotally mounted ,ribs adapted to be folded against the stick and` formed in slidably connected inner and `outer sections, each 'outer section sliding .against ,the lower face ofthe innersection and' `terminating at its inner end in a bifurcatedijbearing, arunner, braces connected at their inner ends tothe runner and having their outer 4ends bifurcated ltovstraddle thebifurcated bearings of the outer rib sections, pivot pins connecting the said bifurcated bearings of lth'e lrib sections and thebifurcated endsiof'the braces,

and spring actuated dogs arranged `within the bifurcated bearingsfof the .rib sections` and mounted upon .the saine pivot lpins which .connect the braces to the rib sections, the inner rib sections being lfformed with notches adapted to be engagedby the dogs when the yribsare extendedandrthe dogs' being provided withv rearward lextensions which are engaged by the bifurcated ends of the braces toautomatically 'release the dogs when ythe runner is moved to swing the ribs against the stick.

In ytestimony whereof I have Lsigned my name to this specification in ythe presence of two subscribing witnesses. CARL O.' YOUYGREN Vitnesses:
